Quicksand Fans

Hi

Came across this small feature in a 1958 book on the cinema, it is about a guy called George Blackwell who ran a special effects department at the time.

Made from rice pudding eh, did we know that?

The movie contains the much-quoted description of quicksand by John Mills:
"Liquid underneath, with a dry crust on top, and a consistency of mouldy rice pudding".
